Year 8 IntoScience Homework Guide Term 3, 2016 A subscription for the Year 8 IntoScience program of $12 will need to be finalised before homework which is worth 10% of a student's final mark can be recorded for terms 3 and 4. If payment is required please contact the student office or pay online through the school's website at http://www.elderslieh.schools.nsw.edu.au/ . Once a receipt has been shown your child will receive a username and password to access the program. Name ______________________________________________________ Class 8SCI Circle one letter A C T I O N Teacher ____________________________________________________ www.intoscience.com.au Username:__________________________________________________ Password:___________________________________________________ EHS Year 8 Science Revision Booklet 2016 Term3 Page 0 This booklet is the term 3 homework guide for the IntoScience activity tasks that are to be completed weekly. The class teacher can view activity within the program and will check on your child's progress. These online tasks reinforce the key ideas and skills taught in the science classroom. All learning activities completed throughout the year, including this revision booklet, contribute towards your grading in the Science course. Instructions Students: You are expected to complete all revision online tasks in this booklet by the end of the term. Every week you will have to log onto ‘IntoScience’ using the internet. Sign in using your username and password provided. You are to log in and sign in as yourself and complete doing all your own work, the tasks allocated per week. Navigate to the ACTIVITIES tab at the top. Click on TOPICS to view the "Activity to be Completed". This is listed in the tables that you are required to fill out. Every week there are new activities and you will have to complete all of the activity to earn all your inquiry points. You are to have your parent's check that you are completing each task. It is your responsibility to make sure your parents CHECK and SIGN your homework at the end of each week. You must then bring this homework guide booklet to school for your teacher to CHECK and SIGN at the end of each week. Your teacher has access to view all your activity so please fill in the amount of homework (i.e. inquiry points earned) accurately and honestly. This booklet is my responsibility. If I lose this booklet I can download it from the school's website. I am then responsible for the printing of this booklet. Incompletion of revision tasks or a non-genuine attempt will result in you completing this work during lunch supervision. Some of the skills in this booklet will be used in the yearly examinations, so you are helping yourself succeed by completing the booklet! I have read the above information and am aware of what is required from me and the consequences of not completing my homework revision tasks. Name: ________________________ Signature __________________________ EHS Year 8 Science Revision Booklet 2016 Term3 Page 1 Parents: All learning activities contribute towards your child’s academic achievement. Tasks including this homework guide are used as a regular part of the teaching and learning process to clarify your child’s understanding of concepts, to remedy their misconceptions, and to support their further learning and the development of deeper understanding. You can assist by asking your child to show you the online revision tasks for each week. When the weekly tasks have been completed, please sign the table to indicate they have completed the task for that week. You child will ALWAYS have Science revision. Additional resources: http://www.dec.nsw.gov.au/ to access student portal including email. http://www.boardofstudies.nsw.edu.au/syllabus_sc/science.html Science syllabus documentation http://arc.boardofstudies.nsw.edu.au/go/home/ Information regarding grading can be located at the Board of Studies Assessment Resource Centre. The general performance descriptors for each of the five grade levels is documented in the table below. http://www.clickview.com.au/ Clickview documentaries (access codes via the library) http://www.bbc.co.uk/education BBC Science clips, explanations, quizzes and interactive. The general performance descriptors describe performance at each of five grade levels. The student has an extensive knowledge and understanding of the content and can readily apply this A knowledge. In addition, the student has achieved a very high level of competence in the processes and skills and can apply these skills to new situations. The student has a thorough knowledge and understanding of the content and a high level of B competence in the processes and skills. In addition, the student is able to apply this knowledge and these skills to most situations. C The student has a sound knowledge and understanding of the main areas of content and has achieved an adequate level of competence in the processes and skills. D The student has a basic knowledge and understanding of the content and has achieved a limited level of competence in the processes and skills. E The student has an elementary knowledge and understanding in few areas of the content and has achieved very limited competence in some of the processes and skills. Thank you for your cooperation.
